COMMAND
xfsdump insecure file creation
SYSTEMS AFFECTED
IRIX versions prior to 6.5.20 (6.5.20 is immune)
PROBLEM
In SGI Security Advisory 20030404-01-P:
It's been reported that xfsdump creates quota information files
insecurely, possibly leading to a root exploit by a local user.
See: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0173
SGI has investigated the issue and recommends the following steps for
neutralizing the exposure. It is HIGHLY RECOMMENDED that these measures
be implemented on ALL vulnerable SGI systems.
These issues have been corrected with patches and in future releases of
IRIX.
SOLUTION
There is no effective workaround available for these problems if you
need to use xfsdump on xfs filesystems with quotas. SGI recommends
either upgrading to IRIX 6.5.20 (when available), or installing the
appropriate patch available from vendor.
